Protection & Drainage

20160726_104007

Geotextile

Geotextile Fabrics are used to provide effective separation and protection between soil and hardcore layers whilst allowing the flow of moisture. The geotextile fabrics can act as a strong barrier to particles whilst still allowing free drainage. This prevents soil from slumping in constructions such as artificial islands, embankments and cuttings.

Geotextile fabrics also prevent the ingress of particles into drains and outlet pipes. Often underground permeable pipes will be wrapped in geotextile to prevent them becoming clogged up over time.

Virgin fibre polypropylene

Virgin fibre polypropylene

High tenacity non-woven Virgin Fibre Polypropylene geotextile fabrics for heavy duty applications.

Permeable membrane allows water flow but ensures particles are kept in place.

Main characteristics:

  • High strength
  • Superior production techniques
  • Highest quality raw material
  • No staples or glues
  • Uniform and consistent strength throughout the roll
  • No weak spots
  • High tensile strength
  • High puncture strength
  • High temperature resistance
  • Screws can pass through fabric without furring up

Two types of Virgin Fibre Polypropylene geotextile available, PPST high tenacity fabric and PPEXT.

 

Jumbo rolls

6 metre wide rolls are ideal for road and rail construction. Faster and stronger drainage / stabilisation layer. Less individual rolls mean fewer joints:

  • Less joints to seal means labour saving
  • Less overlap means less material wastage
  • Fewer joints means a stronger layer

If you are unsure what to use just speak to a member of the team.

Recycled polyester

Recycled polyester

Wallbarn supplies two ranges of nonwoven RECYCLED POLYESTER geotextile fabrics, offering environmental sustainability benefits as well as cost savings.

Available:

  • densities from 100gsm up to 1500gsm
  • roll sizes from 1m to 6m wide

A cost-effective solution for soil stabilisation, filtration projects and lower level protection. They have a lower tensile strength than virgin fibre polypropylene fabrics and are used on installations with less ground movement and lower abrasion force.

Two types of recycled polyester fabric:

  • PEIT – suitable for lower level protection and separation
  • PECT – suitable for separation and filtration

 

Our PECT recycled polyester fabric is ideal for green roof construction as a separation and filtration layer. between drainage membranes and soil substrates. Please see our green roof page for more details.
